Print verification database mechanism

Abstract

A method is disclosed. The method includes reading image data from a print medium and performing image processing on the image data by querying a database to verify that each object to be included on the print medium appears on the medium in a manner in which it is supposed to appear.

What is claimed is: 
     
       1. A print verification system comprising:
 one or more image readers to read image data from a print medium; 
 a database including one or more print job objects that are to be included on the print medium; and 
 a processor to perform image processing on the read image data by querying the database to verify that each print job object included in the read image data appears on the print medium in a manner according to object rules and criteria specified in the database, wherein an object rule includes information regarding a desired coordinate placement of a print job object and a criterion provides a desired print quality for the print job object. 
 
     
     
       2. The print verification system of  claim 1  wherein the database object rules and criteria are generated from an analysis of print page data prior to application of ink to the print medium. 
     
     
       3. The print verification system of  claim 1  wherein an object rule includes information regarding object combinations. 
     
     
       4. The print verification system of  claim 1  wherein an object rule includes information regarding color values for an object. 
     
     
       5. The print verification system of  claim 4  wherein the processor verifies that the object includes color values indicated by the object rule. 
     
     
       6. The print verification system of  claim 1  wherein the database further comprises criteria metric. 
     
     
       7. The print verification system of  claim 6  wherein a criteria metric is implemented to examine general object properties. 
     
     
       8. The print verification system of  claim 7  wherein the general object properties comprise one of proportion, color, sheet cuts, or shifted planes. 
     
     
       9. The print verification system of  claim 6  wherein a criteria metric is implemented to examine detailed object properties. 
     
     
       10. The print verification system of  claim 6  wherein a criteria metric is implemented to determine legibility of an object. 
     
     
       11. A method comprising:
 reading image data from a print medium; and 
 performing image processing on the read image data by querying the database to verify that each print job object included in the read image data appears on the print medium in a manner according to object rules and criteria specified in the database, wherein an object rule includes information regarding a desired coordinate placement of a print job object and a criterion provides a desired print quality for the print job object. 
 
     
     
       12. The method of  claim 11  wherein the database object rules and criteria are generated from an analysis of print page data prior to application of ink to the print medium. 
     
     
       13. The method of  claim 11  wherein an object rule includes information regarding object combinations. 
     
     
       14. The method of  claim 11  wherein an object rule includes information regarding color values for an object. 
     
     
       15. The method of  claim 11  wherein image processing further comprises querying the database to verify that each object appears on the print medium in accordance with one or more criteria metrics. 
     
     
       16. The method of  claim 15  wherein a criteria metric is implemented to examine general object properties. 
     
     
       17. The method of  claim 15  wherein a criteria metric is implemented to determine legibility of an object.
